The various processes in nitrogen cycle are-
(i)Fixation - It is the first step in the process of making nitrogen usable by plants. Here bacteria change nitrogen into ammonium.
(ii)Nitrification - This is the process by which ammonium gets changed into nitrates by bacteria.
(iii)Assimilation - This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll.
(iv)Ammonification - It is the decaying process. When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
(v)Denitrification - The denitrifying bacteria break down nitrates and return nitrogen in the air.

- name the microorganism which can fix atmospheric nitrogen in the soil
- How is nitrogen fixd in lightning
- name nitrogen fixing bacteria
- which bacteria does not fix nitrogen a]clostridium b]rhizobium c] azotobacter d]nitrosomonas I clicked clostridium but is given as wrong and the right answer is nitrosomonas how it is possible as clostridium is a bad bacteria?????!!!!!!
